Key Aroma and Smoke Components Influencing Heated Tobacco Product Sensory Quality

Three tobacco types—flue-cured, sun-cured yellow, and sun-cured red—from multiple producing regions were analyzed to identify components affecting sensory quality. Palmitic acid and chlorogenic acid were positively correlated with overall sensory scores, while citric acid and several furan and nitrogen-containing components were linked to negative qualities like irritancy and bitterness. The dataset, last updated May 4, 2026, was created by Tong Wang and shared under a CC-BY-4.0 license.

Use Cases

• Screen tobacco raw materials for heated tobacco products based on identified key aroma components.
• Model relationships between chemical components (fatty acids, polyphenols) and sensory attributes like irritancy or dryness.
• Optimize product formulations by targeting components negatively correlated with sensory quality.
• Perform canonical correlation analysis to explore links between leaf aroma components and smoke component profiles.

Strengths

• Analysis includes three distinct tobacco types (flue-cured, sun-cured yellow, sun-cured red) from multiple producing regions.
• Key components were identified using orthogonal partial least squares discriminant analysis (OPLS-DA) and correlation methods.
• The dataset is openly shared under a permissive CC-BY-4.0 license.

Limitations

• The dataset is very small at 31.8 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
